..In summary, we have identified a discrete subset of cysteines that are likely to be involved in the functional response of RyR1 to different redox modifications (S-nitrosylation, S-glutathionylation, and oxidation to disulfides)...

..Our data are consistent with a model in which apoCaM binding to the region around the IQ motif is necessary for the rapid binding of Ca(2+) to the C-lobe of CaM. Upon Ca(2+) binding, this lobe is likely to engage the A-C region...

..This review addresses the functional regulation of Cav1.2 and Cav2.1 by calmodulin and discusses how Ca2+ binding to a single calmodulin molecule can regulate opposing functions of the voltage-gated Ca2+ channels...

..We propose a feed-forward cyclic mechanism that increases the temperature sensitivity of RyR1 activation and underlies heat stroke and sudden death. The cycle eventually produces a myopathy with damaged mitochondria...

..Those residues appear to allow an interaction with calmodulin with one lobe Ca(2+)-bound and one lobe Ca(2+)-free. Our data also provide evidence for lobe-lobe interactions in calmodulin bound to Ca(V)1.2...

Suramin interacts with the calmodulin binding site on the ryanodine receptor, RYR1

..In conclusion, Ca(2+)-calmodulin assumes a novel conformation when part of a complex with the C-terminal tail of the Ca(V)1.2 alpha(1) subunit that is not duplicated by synthetic peptides corresponding to the putative binding motifs...

A noncontiguous, intersubunit binding site for calmodulin on the skeletal muscle Ca2+ release channel

..This review addresses the functional regulation of Cav1.2 and Cav2.1 by calmodulin and discusses how Ca2+ binding to a single calmodulin molecule can regulate opposing functions of the voltage-gated Ca2+ channels...

The skeletal muscle Ca2+ release channel has an oxidoreductase-like domain

..6 could play a role in heart failure, CPVT, and ARVD2. Also discussed are the consequences of FKBP12 depletion to skeletal muscle and the possibility of FKBP12 involvement in certain forms of MH or CCD...
